Ingredients
Method
- Preheat oven to 350°F (175°C). Grease two 9-inch round pans, line with parchment. Whisk flour, cocoa, baking soda, and salt.
- Cream 1/2 cup butter and sugar 2 minutes until pale. Beat in eggs one at a time, then vanilla.
- On low, alternate adding buttermilk and dry ingredients, mixing just until combined (about 1 minute). Do not overmix.
- Stir in food coloring and vinegar, then gently fold in 1 cup crushed Oreos until evenly scattered.
- Divide batter between pans, smooth tops, and bake 25-30 minutes until a toothpick tests clean. Cool in pans 10 minutes, then invert onto a rack to cool completely.
- For frosting, beat cream cheese and 1/2 cup butter 2 minutes. Gradually beat in powdered sugar and vanilla, then fold in 1/2 cup crushed Oreos. Frost the cooled cake, decorate with extra cookies, and serve.
Notes
Cooling time not included in prep or cook estimates; allow about 1 hour for the layers to cool before frosting. The cake can be made a day ahead and stored frosted in the fridge. Bring to room temperature before serving for the softest crumb.
